New megaliths found in Jordan in various stages of construction which helped archaeologists suggest a method for their construction by carving the stones from the ground and then supporting them with smaller ones.

Worth checking to see if standing stones may have been found at these sites as well.

The first use of dolmen in an archaeological context was in Théophile Corret de la Tour d’Auvergne's Origines gauloises (1796) to describe megalithic tombs.
